2sin^2(pi/6 )+c o s e c^2((7pi)/6)cos^2(pi/3)=3/2

Prove that: (a) 2sin^(2)(pi/2) + "cosec"^(2)((7pi)/2) cos^(2)(pi/3)=(3/2)^2 (b) 2sin^(2)((3pi)/4)+2cos^(2)(pi/4)+2sec^(2)(pi/3)=10

2(sin^(2)(pi/6)) +"cosec"(7pi)/(6)cos^(2)pi/3=3/2

Prove that: 2sin^(2)(pi)/(6)+csc^(2)(7 pi)/(6)cos^(2)(pi)/(3)=(3)/(2)

2sin^(2)((pi)/(6))+cos ec^(2)(7(pi)/(6))(cos^(2)pi)/(3)=(3)/(2)
